hw/ufs: Add temperature event notification support

This patch introduces temperature event notification support to the UFS
emulation. It enables the emulated UFS device to generate
temperature-related events, including high and low temperature
notifications, in compliance with the UFS specification.

With this feature, UFS drivers can now handle temperature exception events
during testing and development within the emulated environment.
This enhances validation and debugging capabilities for thermal event
handling in UFS implementations.
